In an endoscope objective lens which includes a reflective member that bends an optical path substantially at a right angle inserted between the last lens surface and an image sensor disposed on the image plane, the effective diameter of the last lens surface is made smaller than the size of the image sensor in a direction corresponding to the optical path bending direction and the endoscope objective lens is made so as to satisfy a conditional expression given below.h1<；V+0.4 (1)
